2. JSON Grammar (JSON语法)

A JSON text is a sequence of tokens. The set of tokens includes six structural characters, strings, numbers, and three literal names.

JSON文本是一个token序列。token集合包括六个结构字符、字符串、数字和三个字面量名称。

A JSON text is a serialized value. Note that certain previous specifications of JSON constrained a JSON text to be an object or an array. Implementations that generate only objects or arrays where a JSON text is called for will be interoperable in the sense that all implementations will accept these as conforming JSON texts.

JSON文本是一个序列化的值。注意，JSON的某些早期规范将JSON文本限制为对象或数组。在需要JSON文本的地方只生成对象或数组的实现将是互操作的，因为所有实现都会接受这些作为符合规范的JSON文本。

JSON-text = ws value ws

These are the six structural characters:

以下是六个结构字符：

begin-array     = ws %x5B ws  ; [ left square bracket (左方括号)

begin-object    = ws %x7B ws  ; { left curly bracket (左花括号)

end-array       = ws %x5D ws  ; ] right square bracket (右方括号)

end-object      = ws %x7D ws  ; } right curly bracket (右花括号)

name-separator  = ws %x3A ws  ; : colon (冒号)

value-separator = ws %x2C ws  ; , comma (逗号)

Insignificant whitespace is allowed before or after any of the six structural characters.

在六个结构字符中的任何一个之前或之后都允许无意义的空白字符。

ws = *(
        %x20 /              ; Space (空格)
        %x09 /              ; Horizontal tab (水平制表符)
        %x0A /              ; Line feed or New line (换行符)
        %x0D )              ; Carriage return (回车符)
